For example, geckos can grip almost any surface--including walls and ceilings--with their amazing toes. And when collector urchins are attacked, they release tiny, sharp objects that bear a striking resemblance to throwing stars. You will also meet the scientists who are studying these...

For hundreds of years, people found the fossils of ancient sea creatures at the tops of tall mountains. Scientists puzzled over this problem. A fish couldn't have swum up a mountain. And how could rocks on a mountain move up from the bottom of a sea? Geologists finally found the answers they needed in the 1960s, when they developed the theory of plate tectonics. This theory revolutionized our understanding of the earth. Plate tectonics explains how...

In the 1880's, science witnessed a major shift: Charles Darwin proposed his theory of evolution. People dug up the first dinosaur fossils. And the field of paleontology-the study of ancient plants and animals-emerged. Othniel Charles Marsh and Edward Drinker Cope became enthralled with these new ideas, discoveries, and developments. Both were determined to become world-famous paleontologists. When they met in 1863, they started off as friends. But...
